Is the little reflection a ghost?
The green streak in "Jupiter's reflection" makes it much more likely to be caused by a passing boat (going from left to right given the color):

Why is there ghosting when using flash on tripod with image stabilization?
Looks like it's related to image stabilization as Tetsujin suggested. Managed to replicate the issue. Switched off the IS and the Ghosting went away. It is a new IS lens (Latest Sigma 105mm macro IS)....

Why do my mobile phone images have a ghostly glow?
The effect you are seeing is usually called "halation" or "bloom", and on the face of it, it seems obviously caused by the lens protector. Take it off, and compare.

What is causing the "bright spot" artifact in my picture?
This artifact falls under the heading of flare / ghost image. It is caused by internal reflections. The camera lens is a complex array of multiple polished glass lens elements. Some elements are ...

Why do my mobile phone images have a ghostly glow?
It's almost certainly the protector and/or smudges on either the protector or the original surface before the protector was applied. Most smudges are caused by skin oil in fingerprints. The oil on the ...

What is the cause of a dimmer image of a light source in a photo?
That is most likely the result of an internal reflection between different elements in your lens. Modern coatings can reduce and/or eliminate a lot of internal reflections, but all bets are off when ...

What is this green dot near the light in this photo and what's causing it?
Those are reflections of the lights. The most common cause of this is using a filter in front of the lens since its flat surface makes reflection easier to occur and in a more predictable pattern. The ...

Not necessarily. The difference could have been something else only tangentially related to ...

As you know, the camera lens is fabricated using numerous lens elements, each with two polished glass surfaces. Now polished glass reflects away about 5% of the light. This reflected light is lost so ...

This is a type of lens flare called "ghosting". A UV filter can certainly cause it to be strongly visible, although it can happen without as well. A UV filter can be useful protection if you are in a ...

What could cause this visible artifact which seems to a be a glowing inverse of something outside of the frame overlayed on this photograph?
I agree with @Michael Clark 's answer.
I used Google Earth to get a better angle, cropped, rotated 180°, and superimposed.
Here's the result:

In general, lenses with superior anti-reflective coatings will reduce the influence of brighter light sources to create flare and reflections within the frame of an otherwise darker scene.
